Add coverage in particular for dateStyle: undefined and timeStyle:
undefined, and for dateStyle applying to PlainMonthDay/PlainYearMonth
which were not tested.
"islamic" is underspecified because it doesn't include any information
which location and algorithms should be used to approximate new moon
observations. Instead switch to "islamic-tbla".
Adds a test for each Temporal object's toLocaleString() method, formatting
them with only one option e.g. { year: 'numeric' } and comparing it with
the corresponding output for legacy Date.
See tc39/proposal-temporal#2796.
Tweak some tests to provide coverage of new execution paths in the spec,
such as calling GetOptionsObject inside ToTemporal___; add a few new tests
for things that weren't covered before, such as rounding a PlainDateTime
at the edge of the range; and tweak the tests verifying when the
properties of the options bag are read, which I made a mistake in #4119.

Previously getISOFields() was used to get the exact value of the
[[Calendar]] and [[TimeZone]] internal slots, as well as to get the
reference ISO year for PlainMonthDay and reference ISO day for
PlainYearMonth.
Use calendarId and timeZoneId for the former and toString() for the
latter.
Without custom calendars and time zones there are actually a bunch of
things that we now can't test on implementations that don't have non-ISO
calendars or non-UTC time zones. (Alternatively, we can say that these are
functionalities that those implementations don't have to implement.)
Following the upstream ECMA-402 change tested in the previous commit, add
test coverage for the corresponding functionality in Temporal. Fix one
test that was erroneous.
For each Temporal type, add a test (which should not be sensitive to the
exact locale format) that ensures dateStyle affects the output, for a
Gregorian and non-Gregorian calendar.
See https://github.com/tc39/proposal-temporal/issues/2058
I wrote a similar test for Temporal.ZonedDateTime.p.toLocaleString, so
while this was fresh I decided to do the same for the other toLocaleString
calendar mismatch tests that were in staging.
Unfortunately, in #3304 I made a last-minute mistake when I added the
uncallable value to the assertion message, and neglected to test it;
Symbols can't be converted to strings like that, so these tests would
fail. This fixes the assertion messages.

In a previous version of the specification, there was a fallback to the
intrinsic getOffsetNanosecondsFor when it was undefined.
